Application April 20, 1953, Serial No. 349,743

2 Claims. (Cl. 210-51) This invention relates to improvements in pitchers and more particularly to pitchers which may optionally be utilized for separating two liquids having different densities.

In the pursuit of the culinary art, it often becomes necessary and advisable to separate two liquids having different densities or a liquid from a solid.

It is a prime object of the invention to provide an improved pitcher having means therewith for permitting the separation of two liquids of different densities or other objects which ordinarily seek different levels one respective the other when they are inter-mixed.

It is a further object of the invention to provide an improved gravity separator which is economical to manufacture and positive in operation.

Other objects and advantages of the invention will be obvious to those skilled in the art from a reading of the following specifications taken with reference to the drawing wherein:

Figure l is a top view of the invention.

Figure 2 is a side sectional view taken along line 2-2 of Figure 1.

Figure 3 is a fragmentary view illustrating one portion of a retaining member.

Figure 4 is a fragmentary view indicating a cooperating member for fastening the cap of the invention to the body of the pitcher.

Figure 5 is a top view of the cap incorporated in the invention.

Figure 6 is a side sectional view taken along line 6-6 of Figure 5.

Referring to the drawing in detail, the invention comprises a pitcher 10 formed with a base 12 and a cylindrical upright wall 14 extending from said base. Cylindrical wall 14 is further provided with a handle 16 and a spout 18. A plurality of first retainer members 20 are formed, and disposed at spaced apart intervals around the upper outer extremities of wall 14.

A cap member 22 is formed with a cylindrical wall 24 which is of proper diameter to snugly fit within cylindrical wall 14. Cap member 22 is further provided with a top member 26 which covers substantially half of the open cross sectional area of said cap 22, and extends beyond the confines of the wall. Depending from said top member 26 are a plurality of cooperating second retainer members 28 are adapted to engage said first'retainer members 20 and maintain the cap in close contact with the side walls 14 of pitcher 10. The cap member 22 and side wall 14 are formed with close fit cooperating angular rims such as 30 and 32.

In operation the cap member 22 is placed in a position suitable for pouring the contents of the container. This may be in a position with the opening of the cap diametrically opposite to the position of the handle or at right angles with respect to said handle position. The position may further be determined by the placement of retainer members 20 and 28.

It is obvious from the drawing that the cap member 22 is formed with a side wall 24 of sufficient length to permit the same to close off the spout 18 from the remainder of the pitcher, so that as the pitcher is turned from a longitudinal axis to a lateral or horizontal axis, no liquid will pass from the pitcher through the spout in operation, the tilting of the pitcher permits the liquids of lower density to be poured off as said liquids of lower density have a tendency to rise at the uppermost surface of a mixture of liquids.

In the event it is desirable to remove the cap, it need merely be given a turn with respect to the pitcher.

Having thus described my invention, it is obvious that modification from the illustrative embodiment will be obvious to those skilled in the art. I desire that the appended claims be interrupted within the spirit and scope of the invention.

What is claimed is:

l. A liquid density separator including a base member, a first body member of pre-determined internal diameter extending upwardly from said base member, a handle and a spout secured to said first body member, and a cap member, said cap member including a second body member having an exterior diameter substantially equal to the diameter of said first body member, and a top member, said top member forming a closure for substantially half of said cap member, said second body member extending within said first body member and closing said spout.

2. A liquid density separator including a base member, a first cylindrical body member of predetermined internal diameter extending upwardly from said base member, a handle secured to said body member, and a spout communicating with an opening formed in said first cylindrical body member, a plurality of first retaining members extending outwardly from said first cylindrical body member proximate the periphery of said body member remote from said base member, and a cap member, said cap member including a second cylindrical body member having an external diameter substantially equal to the internal diameter of said first cylindrical body member, a top member including a straight edge extending across said top member to form a closure for substantially half of said cap member, and a plurality of second retaining members extending downwardly from said cap member and formed to cooperate with said first retaining members to lock said cap member to said first body member, and said second cylindrical body member extending within said first cylindrical body member when locked to close off said spout.
